1. A wiring harness comprising:
an insulated wire; and
a water blocking material that covers an exposed conductor part of the insulated wire,
wherein the water blocking material is a cured product of a composition containing a urethane (meth)acrylate having a polycarbonate chain and a (meth)acrylate and has two or more glass transition points,
a content of the urethane (meth)acrylate in the composition is 30 parts by mass or more and 80 parts by mass or less,
the composition further contains an acylphosphine oxide-based photopolymerization initiator and an alkylphenone-based photopolymerization initiator, and
the composition contains 0.1 part by mass or more and 1.0 part by mass or less of the acylphosphine oxide-based photopolymerization initiator and 0.5 parts by mass or more and 3.0 parts by mass or less of the alkylphenone-based photopolymerization initiator.
